Talzhemir (also called 'Manda or Penumbra) is a furre and artist. She is the author of the original canon material that underlies the game[clarify] (such as the Primes) and many of its signature terms (such as "furre"). She made most of the standard and Silver Sponsor patches for Furcadia, where she is marked as a feline, although her true species may be otherwise.

She is the co-creator of "Pocket Universe" which is the "house engine" of the company UNIgames. It forms the core of the tabletop roleplaying games "Quicksilver Lite" and "Bethorm the Plane of Tekumel®"
